DĂ©cision de groupe, Aide Ă la facilitation : ajustement de procĂ©dure de vote selon le contexte de deÌcision
La facilitation est un Ă©lĂ©ment central dans une prise de dĂ©cision de groupe surtout en faisant l'usage des outils de nouvelle technologie. Le facilitateur, pour rendre sa tĂąche facile, a besoin des solutions de vote pour dĂ©partager les dĂ©cideurs afin d'arriver Ă des conclusions dans une prise de dĂ©cision. Une procĂ©dure de vote consiste Ă dĂ©terminer Ă partir dâune mĂ©thode le vainqueur ou le gagnant dâun vote. Il y a plusieurs procĂ©dures de vote dont certaines sont difficiles Ă expliquer et qui peuvent Ă©lire diffĂ©rents candidats/options/alternatives proposĂ©es. Le meilleur choix est celui dont son Ă©lection est acceptĂ©e facilement par le groupe. Le vote dans la thĂ©orie du choix social est une discipline largement Ă©tudiĂ©e dont les principes sont souvent complexes et difficiles Ă expliquer lors dâune rĂ©union de prise de dĂ©cision. Les systĂšmes de recommandation sont de plus en plus populaires dans tous les domaines de science. Ils peuvent aider les utilisateurs qui nâont pas suffisamment dâexpĂ©rience ou de compĂ©tence nĂ©cessaires pour Ă©valuer un nombre Ă©levĂ© de procĂ©dures de vote existantes. Un systĂšme de recommandation peut allĂ©ger le travail du facilitateur dans la recherche dâune procĂ©dure vote adĂ©quate en fonction du contexte de prise de dĂ©cisions. Le sujet de ce travail de recherche sâinscrit dans le champ de lâaide Ă la dĂ©cision de groupe. La problĂ©matique consiste Ă contribuer au dĂ©veloppement dâun systĂšme dâaide Ă la dĂ©cision de groupe (Group Decision Support System : GDSS). La solution devra sâintĂ©grer dans la plateforme logicielle actuellement dĂ©veloppĂ©e Ă lâIRIT GRUS : GRoUp Support.Facilitation is a central element in decision-making, especially when using new technology tools. The facilitator, to make his task easy, needs voting solutions to decide between decision-makers in order to reach conclusions in a decision-making process. A voting procedure consists of determining from a method the winner of a vote. There are several voting procedures, some of which are difficult to explain and which may elect different candidate/options/alternatives proposed. The best choice is the one whose election is easily accepted by the group. Voting in social choice theory is a widely studied discipline whose principles are often complex and difficult to explain at a decision-making meeting. Recommendation systems are becoming more and more popular in all fields of science. They can help users who do not have sufficient experience or competence to evaluate large numbers of existing voting procedures. A recommendation system can lighten the facilitator's workload in finding an appropriate voting procedure based on the decision-making context. The objective of this research work is to design such recommendation system. This work is in the field of group decision support. The issue is to contribute to the development of a Group Decision Support System (GDSS). The solution will have to be integrated into the software platform currently being developed at IRITGRUS: GRoUp Support
Choosing a Voting Procedure for the GDSS GRUS
In group decision-making, the use of Group Decision Support Systems is increasing and in some groups, a facilitator is required to improve communication among participants. The facilitator has several roles in this situation, which include helping decision makers (DMs) to decide which type of aggregation they would prefer in each decision context. Whenever DMs have different objectives regarding the same problem, they might decide a consensual decision is no longer possible. Therefore, other types of aggregation are required. Voting rules are strongly applied in this type of situation. However, the question that arises is: who should decide the voting method? In this article, a framework for choice of a voting procedure in a business decision context is used. It takes the facilitatorâs preferences into account while it seeks to choose which voting procedure best suits the environment of the Group Decision Support System GRoUp Support (GRUS)
